PROBLEM TO BE SOLVED: To provide an intake system capable of inhibiting pressure loss at a confluent part between a short port and a long port.SOLUTION: An intake system 100 includes: an intake port 2; a valve 31 that contains a closing part 34 for closing an opening 25 of the intake port 2 and rotates between an opening position using a short port 2b of the intake port 2 and a closing position using a long port 2a of the intake port 2; an actuator 32 that rotates the valve 31; and a current plate 5 at least provided at a part different from the closing part 34 in the valve 31 or on the downstream side of the valve 31 and the upstream side of a confluent part 24 between the short port 2b and the long port 2a, the plate leading a direction of fluid flowing in the short port 2b to the downstream side of the confluent part 24. |
